ADP4000

www.DataSheet4U.com ADP4000 Product Preview Programmable Multi- Phase Synchronous Buck Converter with PMBus The ADP4000 is an integrated power control IC with a PMBus interface. The ADP4000 can be programmed for 1-, 2-, 3-, 4-, 5- or 6phase operation, allowing for the construction of up to six complementary buck switching stages. The ADP4000 supports PSI, which is a power state indicator and can be used to reduce number of operating phases at light loads. The ADP4000 includes a PMBus interface, which can be used to program system set points such as voltage offset, load line, phase balance and output voltage. Key system performance data such as CPU current, CPU voltage, and power and fault conditions can also be read back over the PMBus from the ADP4000.
